PPLN (ridge) waveguide

The waveguide can be manufactured on a periodically poled crystal to form a frequency conversion waveguide. HCP provides two types of the waveguide to customers to satisfy the requirement of the different applications.

Compared to the traditional ion or proton in-diffused waveguide, the ridge waveguide has a high damage threshold and wide-operation wavelength range due to the high refractive index difference of the core (LiNbO3) and the cladding. The good confinement leads to good conversion efficiency and feasibility of extremely low propagation losses.

Most of the waveguides are manufactured upon request, but some of them are available in stock for popular applications. See the typical specification below and just inquiry us with your specific wavelength.

Following table shows the typical specifications of the standard waveguide, for ordering:
